Hi my name is page and I have a Greek Tortoise named Donatello that I bought from a local pet store less than a year ago. We recently went on vacation and left him with a friend. Since we picked him up he hasn't been eating and hasn't really been moving around like he usually does. Do Greeks hibernate or is something wrong with him.

Thanks

Most Greeks do hibernate.
My greeks whom I am not hibernating this year tend to slow down a little now. But in order to get a better idea of whats going on we need to know more. What type is he? Where are you located? Is he inside the house? What is his Habitat set up? Was he in this when you were on vacation? What are the temps you have him at? What was he fed while you were gone? If you could just fill us in on him it would help.
